Updates for wave coupling in NUOPC

[JessicaMeixner-NOAA]

• add exports of PSTOKES for WW3->MOM6 coupling
• add ice value for surface roughness and FLD2 to switch
• add FieldFill and FieldGather to the timings of wmesmf
• Updates to compile wmesmf after PR#189
• Updating Stokes partitions calculation to make sure there are
  default values

This will close issue #191

Results from regression tests will be added when completed.

The above are two sets of comparisons, the first set and then after PR#194 went through.
The first set of regression tests have the expected differences:

mww3_test_03/./work_PR3_UQ_MPI_e (1 files differ)

mww3_test_03/./work_PR1_MPI_d2 (7 files differ)
mww3_test_03/./work_PR3_UNO_MPI_e_c (1 files differ)
mww3_test_03/./work_PR3_UQ_MPI_d2_c (8 files differ)
mww3_test_03/./work_PR3_UQ_MPI_d2 (8 files differ)
mww3_test_03/./work_PR3_UQ_MPI_e_c (1 files differ)
mww3_test_04/./work_PR3_UQ_MPI_NC_b_c (2 files differ)
mww3_test_07/./work_PR3_UQ (3 files differ)
ww3_tp2.10/./work_MPI_OMPH (7 files differ)

The second set has a few unexpected outfiles with differences, but I did not see any meaningful differences.
